Proof step 5 from proof payload-mod (previous step)

m + nused0 < # zbrar, sorted(zbrar, m, nused0 + 1), n ≤ nused0, ∀ n, zbrar, m, adr. n < nused0 ∧ sorted(zbrar, m, nused0) ∧ m + nused0 ≤ # zbrar → payload(zbrar[m + n, mkzentry(zbrar[m + n].key, adr)], m, nused0) = payload(zbrar, m, nused0)[zbrar[m + n].key, adr] ⊦ payload(zbrar[m + n, mkzentry(zbrar[m + n].key, adr)], m, nused0 + 1) = payload(zbrar, m, nused0 + 1)[zbrar[m + n].key, adr]

Proof step 6:
n = 0, m + nused0 < # zbrar, sorted(zbrar, m, nused0 + 1), n ≤ nused0, ∀ n, zbrar, m, adr. n < nused0 ∧ sorted(zbrar, m, nused0) ∧ m + nused0 ≤ # zbrar → payload(zbrar[m + n, mkzentry(zbrar[m + n].key, adr)], m, nused0) = payload(zbrar, m, nused0)[zbrar[m + n].key, adr] ⊦ payload(zbrar[m + n, mkzentry(zbrar[m + n].key, adr)], m, nused0 + 1) = payload(zbrar, m, nused0 + 1)[zbrar[m + n].key, adr]
Proof step 14:
n = n0 +1, m + nused0 < # zbrar, sorted(zbrar, m, nused0 + 1), n ≤ nused0, ∀ n, zbrar, m, adr. n < nused0 ∧ sorted(zbrar, m, nused0) ∧ m + nused0 ≤ # zbrar → payload(zbrar[m + n, mkzentry(zbrar[m + n].key, adr)], m, nused0) = payload(zbrar, m, nused0)[zbrar[m + n].key, adr] ⊦ payload(zbrar[m + n, mkzentry(zbrar[m + n].key, adr)], m, nused0 + 1) = payload(zbrar, m, nused0 + 1)[zbrar[m + n].key, adr]
